My current research activity focuses mainly on two axes:1°) Machining of composite materials and multi-stacks: this part focuses on the experimental and numerical studies of the machining (drilling and trimming) of the composite and hybrid materials. The main objectives are the analysis of the damage generated during machining and the material integrity vs. the machining process and the parameters of the process. In addition, an analytical models for the prediction of the critical forces responsible of the delamination at the hole exit when drilling is developed. 2°) Instrumentation and manufacturing of composites materials: this part is dedicated to the identification of the variability due to the process of manufacturing thanks to the in-situ instrumentation of the composite materials by optical fiber with Bragg sensor and the digital image correlation. The composite materials concerned are made of natural fibers (flax/epoxy) and synthetic fibers (carbon/epoxy).
